1. Positioning

1.1. Phase One: The Dome of Observation

This phase is extremely short and features only 2 mechanics. The raid can
choose to stack for the extra healing during
Coronal Ejection or position early for the next phase.
Your first (and likely only) Coronal Ejection will
occur about 15 seconds into the encounter. This is the only raid damage during
the phase and lasts 8 seconds. Healers should have no trouble keeping these
players alive, and externals and personal cooldowns are unnecessary.

Etraeus will continually blast the main tank with his
Starburst. No taunt swaps are necessary here, though
it is recommended whichever tank is sturdier should take the boss during this
phase.

1.2. Phase Two: Absolute Zero

At 90% health, Star Augur Etraeus enters Absolute Zero.

The ranged and healers should be spread out across half the room; space for
Shatter is necessary, but be careful not to outrange
your healers. Try to keep the area behind the boss clear, as the melee and
tanks will need this space to deal with the
Absolute Zero debuff.

Anyone affected by Icy Ejection should
ensure they are at least 8 yards away from other players before planting their
feet and awaiting the Shatter. The ranged and healers
should avoid crowding the melee groups so that the melee only have to step out
a few yards for their debuffs, rather than running all the way out to ranged.

The melee and main tank should form an equilateral triangle; two groups of
melee DPS on either side behind the boss. No one, including the current off
tank, should be within a 6-yard radius of the main tank, due to the splash
damage of Etraeus' Iceburst casts. When Etraeus
applies Gravitational Pull to the tank, the tanks
should perform a taunt swap.

The tank with Gravitational Pull should stand
behind the 2 melee stacks, ensuring they are not within a 5-yard radius of any
other players.

The tank must quickly dip into one of the melee stacks, which will clear
the Absolute Zero debuff.

The tank should then step out of the melee group and await the next
Comet Impact.

The tank needs to clear this Absolute Zero in the
other melee stack, or he will freeze the previous group due to their
Chilled debuff.

The tank should continue to alternate between the melee stacks in this
fashion until Gravitational Pull no longer occurs
(after 3 cycles).

When Etraeus begins his cast of Frigid Nova, the
raid should collapse onto the melee stacks to avoid taking fatal damage.

1.3. Phase Three: A Shattered World

At 60% health, Star Augur Etraeus enters A Shattered World.

The melee no longer have to be in separate stacks once you enter this phase.
Etraeus will begin stacking Felburst on his current
target. Assuming no other abilities are taking place, the tanks should perform
a taunt swap every 4 stacks or so.

Gravitational Pull still occurs in this phase. This
now triggers a Fel Impact, which is applied to the
current tank. The Fel Impact should be used to clear
the patches of Felflame dropped by the rest of the
raid. It is particularly important to keep the area around the melee clear,
as their space is restricted.

The boss will now cast Fel Ejection, which begins
occasionally, but will increase in frequency and number of applications the
longer the phase lasts. Players with Fel Ejection
should try and ensure that the puddles of Felflame
they drop cover as small an area as possible. The puddles can overlap with
each other, but they will also deal multiple instances of damage, meaning
this can be dangerous without personal cooldowns or immunities. A good way to
handle Felflame is to take micro steps in a square
pattern, which allows all 4 patches of Felflame to
be easily cleared by a Fel Impact.

When the boss casts Fel Nova, all players should
get to the edge of the room the avoid taking fatal damage.

Towards the end of this phase, space in the room will begin to become very
restricted. The raid must take special care not to use their real estate
poorly, or the raid may become overwhelmed by the pools of
Felflame.

1.4. Phase Four: Inevitable Fate

This phase acts as a "race to the finish". Etraeus will begin to stack
Voidburst on the main tank, which will begin to
proliferate through the raid as the phase progresses. Eventually the entire
raid will be afflicted with the debuff and the stacks will continually
increase over time; at a certain point, healers will no longer be able to keep
up with the damage intake. It is imperative, therefore, that the raid enters
this phase with all DPS alive and cooldowns available. When no other mechanics
prevent taunt swaps (e.g. Gravitational Pull), the
tanks should trade aggro at around 5-7 stacks of
Voidburst. If you trade stacks at low numbers of
Voidburst, the debuff will propagate faster, however, at higher numbers of
stacks the damage might be dangerous to non-tanks.

Void Ejection will cause
Voidlings to be regularly spawned throughout the
phase. These adds are trivial and do not require any special focus; instead,
cleave them down with incidental damage. They have an aggro table and can
be picked up by the tanks, and their melee swings apply stacks of
Voidburst.

The Thing That Should Not Be is the highest priority
in this phase. The group should use Bloodlust on the first add to
eliminate it as quickly as possible, then switch back to the boss. The entire
raid must turn their back to the add during
Witness the Void casts, or be feared for 8 seconds.

When Void Nova is cast, Etraeus will deal weak
raid wide Shadow damage and apply a stack of Voidburst
to all players.
